Hi, I upgraded my Dell Inspiron 1520 to 11.10 and then my wireless network does not work (seems to happen every time I upgrade ubuntu). I have tried the different guides from earlier versions of ubuntu, but nothing seems to work (it seems strange that 4 year old hardware still has problems).

One other thing: After I upgraded the "system" menu in the non-unity desktop has disapeared...

P.S. I do enjoy ubuntu very much, but every 6 month I am about ready to dump it...

Related FAQ:

can you please define what you mean by does not work. What is it doing or not doing ? can you see the wireless menu, can you see your wireless network, does your router have encryption enabled, do you know the password ect ect ect.

also the name and model of the router, and the firmware version (you can find this in the routers admin page)

Hi, I can see the "radar" icon - no signal though. The wireless connection was working before the upgrade. I have multiple wireless routers - Netgear N-300 wnr 2000, a buildin router in my adsl box + plus I used to be able to see 15+ wireless networks in the neigbourhood. I know the password and all, but it is definetly not an issue with the routers.

I have an old harddisk with 10.10 on and it works fine with the wireless network. My Mac also work with no problem. And my Android phone connects to the wireless with no problem.

Please first connect your wired network adapter to the wireless router using an ethernet cable (also known as a LAN cable).

In order to gather essential troubleshooting information about your wireless card, please follow this procedure:

Step 1:

If you are using the Gnome interface, open the Terminal console via "Applications->Accessories->Terminal"

If you are using the Unity interface, the easiest way to open the Terminal is to use the 'search' function on the dash. Or you can click on the 'More Apps' button, click on the 'See more results' by the installed section, and find it in that list of applications. A third way, available after you click on the 'More Apps' button, is to go to the search bar, and see that the far right end of it says 'All Applications'. You then click on that, and you'll see the full list. Then you can go to Accessories > Terminal after that.

Step 2: Please copy-paste the following command from https://help.ubuntu.com/community/WirelessTroubleshootingProcedure in Firefox into the Linux Terminal. Do NOT copy-paste from the Email message into the Terminal, as that will only copy PART of the command. The command STARTS with the word sudo and ENDS with the word lsmod. So please copy-paste the ENTIRE command below from Firefox into a Terminal, press <enter>, then enter password when sudo asks for password, then press enter again.

Tip: If you have a wheel mouse or 3 button mouse you do not need to type commands into the Terminal. Highlight the command written on the page. Move your cursor anywhere in the Terminal and press the wheel or middle button. Automatic Copy and paste! No spelling mistakes! No Typos! No other errors!

Unfortunately that did not work - and it made my lan connection not work... I then opened "system settings" -> hardware - "Additional drivers" and tried to reinstall "Broadcom STA wireless driver". That failed, but it brought back the lan connection!?!
